Collective Heat Act (Wcw): a guide for businesses
Direct answer
The Wet collectieve warmte (Wcw), the Dutch Collective Heat Act, is the new framework for collective heat supply that will replace the 2014 Heat Act. It has been adopted and enters into force in phases. It gives municipalities control over heat networks, requires designated heat companies to be largely publicly owned, and gradually decouples the heat tariff from the gas price under ACM supervision.

Collective Heat Act (Wcw): scattered information versus Energy Intelligence
The Netherlands wants to move away from natural gas, and in densely built neighbourhoods a collective heat network is often the logical solution. Under the old Heat Act, heat networks were largely run by commercial parties and the tariff was tied to the gas price. That gave residents and businesses little grip on price and sustainability. The Collective Heat Act modernises that framework. It matters to anyone connected, or about to be connected, to a heat network: a building owner in a gas-free district, a housing association or a company on a business park.
- The municipality takes the lead: within a designated area, the heat plot, only an appointed heat company will be allowed to transport and supply heat.
- Designated heat companies must be more than half publicly owned, for example by a municipality or province.
- The heat tariff moves step by step away from the gas price towards a tariff based on actual costs, overseen by the regulator ACM.
Insight
Traditional approach
Information is scattered across portals, documents, invoices or separate spreadsheets.
Modern approach
Data, context and interpretation are brought together into a clear decision picture.
Decision-making
Traditional approach
Choices are made based on averages, assumptions or occasional analyses.
Modern approach
Scenarios, KPIs and current measurement data make the trade-off more concrete and repeatable.
Follow-up
Traditional approach
Actions often stay non-committal or disappear into separate reports.
Modern approach
Follow-up actions, monitoring and reporting are linked to the same energy data.
What does the Collective Heat Act regulate?
The Wcw places collective heat under a renewed public framework. The starting point is that the municipality directs the heat transition. No one may supply or transport heat within a municipality without the municipality's permission. The municipality does this by designating an area, the heat plot, and appointing a heat company for it that gets the exclusive task of supplying heat within that plot. In addition, the law requires more public ownership of heat companies, arranges the tariff differently, and sets requirements for security of supply and for making the heat source more sustainable. The goal is to make heat more reliable, more affordable and cleaner.
- The municipality sets heat plots and appoints one heat company per plot.
- Within a plot, the appointed heat company has the exclusive task of supplying and transporting heat.
- The law sets requirements on public ownership, tariff, security of supply and sustainability.
- The Wcw will replace the 2014 Heat Act as the central framework for collective heat.
Why is this law being introduced?
The Dutch government sees collective heat as one of the main routes in the heat transition for the built environment. Taking neighbourhoods off natural gas requires reliable and affordable heat networks that residents and businesses can trust. Under the old Heat Act the heat tariff was linked to the gas price, through the so-called not-more-than-otherwise principle. As a result, heat bills moved with a fossil fuel that the policy is precisely trying to phase out. The Wcw gradually removes that link and works towards a tariff based on the actual costs of construction and maintenance. More public control and public ownership are meant to ensure that the public interest, affordable and sustainable, remains central.
- Moving to gas-free neighbourhoods requires reliable, affordable heat networks.
- The old not-more-than-otherwise tariff tied heat to the gas price; that link is being removed.
- Cost-based tariffs should make residents less dependent on fossil fuel prices.
- Public control and ownership are meant to safeguard the public interest in the heat sector.
What does it mean for a building owner or business?
If you are connected, or about to be connected, to a collective heat network, the municipality becomes your main partner for the route to a gas-free future. Through the heat plot, the municipality determines which heat company may supply heat in your area. Your supplier is then that appointed company, which must meet the new public requirements. For the tariff, the link with the gas price disappears step by step and the regulator ACM oversees the tariffs. Importantly, the tariff regulation is introduced in phases: the exact calculation method is still being worked out over the coming years. So above all, follow the communications from your municipality and your heat company about what changes in your neighbourhood or on your site, and when.
- The municipality decides via the heat plot which heat company supplies your area.
- Your heat supplier must meet the new rules on public ownership and tariff.
- The tariff moves step by step away from the gas price; the ACM supervises it.
- Introduction is phased, so keep an eye on information from your municipality and heat company.
